Argidava (Argidaua, Arcidava, Arcidaua, Argedava, Argedauon, Argedabon, Sargedava, Sargedauon, Zargedava, Zargedauon, Ancient Greek: Ἀργίδαυα, Αργεδαυον, Αργεδαβον, Σαργεδαυον) was a Dacian fortress town close to the Danube, inhabited and governed by the Albocense.

[2] The oldest found potential reference to Argidava is in the form Argedauon or Argedabon (Ancient Greek: Αργεδαυον, Αργεδαβον), written in stone, in the Decree of Dionysopolis (48 BC).

In a later section, the inscription also refers to the Dacian king Burebista and mentions that Akornion was his chief adviser (Ancient Greek: πρῶτοσφίλος, literally "first friend").

Arguments include the name connection with the river Argeș, geographical position on a potential road to Dionysopolis which Akornion followed, and most importantly the size of the archaeological discovery at Popești that hints to a royal palace.

Argidava is mentioned in Ptolemy's Geographia (c. 150 AD) in the form Argidaua (Ancient Greek: Ἀργίδαυα) as an important Dacian town, at latitude 46° 30' N and longitude 45° 15' E (note that he used a different meridian and some of his calculations were off).

Argidava is also depicted in the Tabula Peutingeriana (2nd century AD) in the form Arcidaua, on a Roman road network, between Apo Fl.
